structural feature of many natural products. By using a domino reaction of aromatic amines and cyclicenolethers or 2-hydroxy cyclicether catalyzed by indium chloride in water, various tetrahydroquinoline derivatives were synthesized efficiently. Most cyclization products showed cis selectivity. The use of 2,3-dihydrofuran as the cyclicenolether provided both higher reactivity and cis selectivity than

A highlyefficient method for the synthesis of 1,2,3,4-tetrahydroquinoline derivatives via a molecular iodine catalyzed dominoreaction of anilines with cyclic enol ethers, such as 2,3-dihydrofuran and 3,4-dihydro-2H-pyran, is described. The reaction may proceed through an aza-Diels–Alder process between an in situ generated 2-azadiene and another equivalent of cyclic enol.

A domino reaction of anilines with cyclic and acyclic enolethers induced by catalytic amounts of TBPA+ (5 mol%) was investigated and a series of 2,4-disubstituted-1,2,3,4-tetrahydroquinolines were synthesized. Different from cyclic enolethers, when acyclic enolethers were used in the reaction, they serve as surrogates of acetaldehyde, producing a series of 2-methyl-4-anilino-1,2,3,4-tetrahydroquinolines

Aryl amines react smoothly with cyclic enol ethers such as 3,4-dihydro-2H-pyran (DHP) and 2,3-dihydrofuran (DHF) on the surface of montmorillonite KSF under mild reaction conditions to afford the corresponding pyrano- and furano[3,2-c]quinolines in high yields with high diastereoselectivity.
在温和的反应条件下,芳基胺与蒙脱石KSF表面的环状烯醇醚(例如3,4-二氢-2 H-吡喃(DHP)和2,3-二氢呋喃(DHF))平稳反应,得到相应的吡喃和呋喃[3,2- c ]喹啉具有高收率和高非对映选择性。
